Filed under: Biodiesel , Vegetable Oil , European Union The Association of Municipalities and Counties of Catalonia, Spain (ACM), has announced an agreement with Recicloil, a company that recycles used vegetable oil into biodiesel. The agreement states that the company will provide one liter of free biodiesel to citizens for each 20 liters of used oil people bring in. Recicloil will also provide a free 2,000-liter biodiesel pump (as well stickers) which will be installed for city fleets using this biodiesel. While this is not the first of such networks, as we explained in another post , it's an important partnership. Spaniards tend to throw used oil down the drain, which is not only a waste of an useful resource, but causes lots of problems in water treatment plants. Powering cars seems much smarter.
